Thanks for an interesting plugin, the code looks great!
Would it be possible to fix WP_Query parameters that accept arrays?
For example:
[wqs post_type="post" post__in="206"][/wqs]This results in WP_Query:
[post__in] => 206 (string)Although it should be:
[post__in] => array(206)Also then, this example:
[wqs post_type="post" post__in="206,123,456"][/wqs]Should resolve to:
[post__in] => array(206,123,456)There are also some other parameters that take arrays.
